TILE-111E MOUTHPIECE.

Application filed September 13, 1923. Serial No. 662,516

To all whom it may concern:

Be it known that I, HARRY T. HEALEY, a citizen of the United States, residing at Arnold, in the county of Westmoreland and State of Pennsylvania, have invented new and useful Improvements in Tile-Die Mouthpieces, of which the following is a specification.

This invention relates to mouth pieces for tile dies, and more particularly to a mouth piece specially adapted for use in the manufacture of tile.

One of the main objects of the invention is to provide a mouth piece of simple construction and operation which is well adapt ed for use in connection with tile makingmachines of known type and in which the core can be treated so as to resist the wear or abrasive effect of the clay. A further object is to provide means whereby the tiles are formed with grooves of dovetail cross-section soas to be effectually locked to gether by the mortar used in laying the tiles. A further object is to provide corrugations which may be readily reversed to accommodate wear. Further objects will appear from the detail description.

In the drawings Fig. 1 is. a face view of the mouth piece;

Fig. 2 is a section taken substantially on line 2,2 of Fig. 1;

Fig. 3 is a side view;

Fig. A is a top plan view of one of the corrugations Fig. 5 is a side view of one ofthe corrugations;

Fig. 6 is a top plan view of one of the corner members; i

Fig. 7 is a side view of one of the corner members.

Fig. 8 is a section taken substantially on line 8-8 of Fig. 9;

Fig. 9 is a side view of the core.

The mouth piece includes aflrectangular frame 1. The inner faces of frame 1 are protected by liner plates or strips 2 which are preferably case-hardened, the plates or strips being secured in position bymeans of screws 3 passing through frame 1, or in any other suitable or preferred manner. Abridge 4: extends across the central portion of frame 1 at the inner face-thereof, this bridge being held spaced away from the frame. and being secured to the diein which themouth piece is secured in a known manner. The frame constructed 1n this manner 1s adapted to he secured in the die of a tile machine in a known manner, the clay being forced into and through the barrel of the machine by a feed screw so as to be forced through frame 1.

A core 5 is positioned centrally of, frame 1. This core includes side plates 6 which are arranged about a filler 7 so as to effectually enclose the same. Each of the side plates is provided with inwardly projecting headed pins 8. In forming the core, plates 6 are setup in a suitable frame, after which a tube 9 is positioned centrally of the plates and Babbitt metal inmolten condition is thenpoured into the space between the plates and tube 9 so as to form filler 7. This .pro-' vides very simple and efficient meanslwhereby the core may bequickly and readily formed. This construction permits the plates 6 to be case-hardened so as to effectually resist the wear or abrasive effect oftheclay. After the core has'been made up; inthe manner described, it is'secured in position on bridge 4 by means of a securing bolt 10 which passes through sleeve 9, this bolt being threadedinto the bridge and a washer 16being positioned between the head of the bolt and the outer end of the sleeve. Spacing washers ordiscs 11 are positioned between bridge A and the inner end of sleeve 9 so as to hold the core positioned properly within fram e l. y j

Corrugations 12 are mounted on frame 1 and positioned to form grooves in the material or clay ;whi ch is forced through the frame between core 5 and. the surrounding walls of the frame. Each of these corrugationsis providedwith two heads 13 of substantially triangular shape, these heads being disposed at right angles to each other and connected by a neck 14, The heads 13 have their lateral faces 13 under-cut. and the inner heads of the corrugations, when inoperative position, extend downwardly acrossjthe inner faces of the liner plates 2, the outer heads of the corrugations extending across the upper face of frame 1 or, more correctly, across spacing strips 15 positionedon the frame 1. Clamping plates 16 extend across the outer faces of the outer heads 13 and are forced toward frame 1 by means of screws 17 threaded into the frame,

or in any other suitable or preferred manner thus securely clamping the corrugations in place. Two of the plates 16 are of greater length than the other plates and extend across arms 17 provided at the upper ends of corner members 18 disposed at right angles to the arms, each of these corner members fitting snugly Within one corner of frame 1 and having its inner face transversely concaved, member 18 tapering downwardly or inwardly of the frame.

Preferably, though not necessarily, a deflector 19 is secured by a screw 20, or in any other suitable or preferred manner, to the outer face of one of the plates 6 of the core, this deflector acting in a known manner to prevent the clay from adhering too closely to the core and insuring proper flow of theclay through the die.

By constructing the mouth piece in the manner illustrated and described, all parts subjected to wear can be readily removed, dressed and case-hardened and then replaced, thus providing a die of very long life. In addition, the plates 6 of the core, as

' well as the liner plates and other parts exposed to wear can readily be case-hardened or replaced when desired. When one of the heads of any of the corrugations 12 becomes worn to such an extent as to produce in ferior work, the corrugation can be quickly and easily reversed so as to provide a new working head. In addition, the corrugations can be readily adjusted toward or away from each other so as to vary the distance between the grooves in the tiles produced to suit circumstances. From the above it will be seen that I have produced a tile die mouth piece of very simple and highly efficient construction in which the parts may be readily adjusted and replaced to suit circumstances, and all parts subject to wear can be case-hardened thus greatly increasing the length of life of the device as a whole.

As will be noted more clearly from Figures 1 and 8, one of the plates 6 of the core is disposed at a decided angle or inclination to the other plates. In practice one or more of the plates 6 may be disposed in inclined or angular relation to the other plates. It is a fact well known to experienced tile makers that the consistency and characteristics of the clay discharged from one tile machine may vary considerably from the clay discharged from another tile machine. As the clay is forced through the mouth piece it frequently happens that the clay at one side of the core will flow through the mouth piece at greater or less speed than the clay at the other sides of the core. By adjusting the core so as to present to the clay at the difierent sides thereof lates which are disposed or inclined at di erent angles, the clay can be retarded at the different sides 1,5os,1se

of the core so as to obtain a uniform flow of clay through the mouth piece. This feature is of importance as insuring the production of perfect tiles and accurately facilitating the moulding or forming of the tiles. In this connection the spreader 19 is of material assistance in that it spreads the clay towards the corners of the mouth piece thus insuring proper rounding or forming of the corners and also acting to hold back or retard the clay at the side of the core where the clay would otherwise flow through the mouth piece too quickly. It will be understood, of course, that as many of these spreaders may be. employed as desired though I have found by practice that ordinarily one spreader properly positioned is suificient.

What I claim is 1. In a tile die mouth piece, a frame, a r

core positioned centrally of the frame, corrugating members each including two heads disposed at right angles to each other, the inner heads of said members extending across the inner faces of the walls of the frame and the outer heads extending across the outer face of the walls of said frame, clamping plates extending across the outer faces of said outer heads, and means for forcing said plates toward the frame.

3. In a tile die mouth piece, a frame, a i

core positioned centrally of the frame, corrugating members each including two heads disposed at right angles to each other, the inner heads of said members extending across the inner faces of the walls of the frame and the outer heads extending across the outer face of the walls of said frame, corner members of arcuate cross-section fitting into the corners of the frame and each provided at its outer end with an arm ex tending across the outer face of the frame, clamping plates extending across the outer faces of said outer heads, certain of said plates extending across the outer faces of said arms, and means for forcing said plates toward the frame.

4-. In a core for a tile die, a filler, protecting plates arranged about the filler, and means for detachably securing the plates to said filler.

5. In a core for a tile die, a plurality of plates arranged in angular relation to enclose a space for a filler, said plates being provided with inwardly projecting securing members, and a filler extending about and enclosing said members and acting to secure the plates agalnst relatlve movement.

6. In a core for a tile due, a plurality of plates arranged in angular relation to en close a space for a filler, said plates being provided with inwardly projecting securing members, and a filler formed of fusible material poured into the space between the plates and extending about and enclosing said members and CO-iICiLiIlg therewith to secure the plates against relative movement.

7. In a core for a tile die, a plurality of plates arranged in angular relation to enclose a space for a filler, a tube positioned within said space and spaced away from said plates, and a filler within the space between the plates and the tube, said plates being provided with inwardly projecting headed pins and the filler extending about rugating member for a tile die mouth piece,

said member including two heads disposed substantially atright angles to each other.

10. As an article of manufacture, a corrugating member for a tile die mouth piece, said member including two substantially V- shaped heads disposed substantially at rightangles to each other, and a neck element connecting the bases of the heads.

In testimony whereof I afiix my signature.
